How to use the starting blocks of track and field equipment?
The starting blocks of track and field equipment are used as follows:
When the track is heard, the athlete should go to his/her own track and adjust his/her starting block (the right pedal is in front and one and a half feet behind the starting line, the left pedal is behind, and the front and rear pedal should be the length of his/her left leg).
2. When you hear the command to take positions, the athletes should squat.
3, heard the preparation of the password, the athletes slowly lifted their hips, higher than the height of the shoulder, center of gravity forward, the left foot of the big, the included Angle of the calf into 110 degrees or so.
Look 1.5 meters in front of you and take a deep breath.
4. When a shot or whistle is heard, the athlete should quickly push off the starting blocks with both feet, first straddling the left foot (but not too big), and then speeding out.
I. instructions for use:
1. Position: please note that the starting blocks should be placed at a slight inclination to the inside, so as to suppress the corners.
2. Pedal Angle: pedal board shall be adjusted to its own comfortable and convenient starting Angle (generally, the Angle shall be between 60 degrees and 80 degrees), and some shall be adjusted to 90 degrees, but it is easy to tilt forward too much and cause the starting fall.
3, adjust the spacing, support leg and pedal leg spacing should not be too large, generally support leg heel to pedal leg knee.
4, tilt Angle, the body forward tilt 45 degrees to 65 degrees at the start, not too small (too small is not conducive to the start of the force), not too large (over the general assembly will cause the body to tilt too much to cause the risk of falling) starting hands placed in the supporting leg before the knee about 15 cm, support distance is greater than two shoulders (slightly larger than the width of the shoulders).
Two, the classification of starting blocks: the starting blocks have the connection square tube type, the plastic runway special channel steel connection plastic spray type, the plastic runway special channel steel connection electroplating type, aluminum alloy starting blocks.
In the past, sprints started standing up.
Sheryl, an Australian sprinter, has been troubled by a lack of success in sprinting.
He observed that the kangaroo, although it had a big bag and a big belly, could run more than 70 kilometers an hour and jump up to 12 meters.
Sheryl noticed that kangaroos always bend down before jumping, bringing their bellies to the ground, and then jump to their feet.
Sheryl invented the squat start by imitating the kangaroo, and he did well in the 1896 Olympics.
Later, many athletes followed suit.
For example, another athlete booker dug a small shallow hole where he squatted on the starting line and put one foot into the shallow hole. When he kicked off, he shot out like an arrow, achieving a time of less than 10 seconds in the 100-meter dash.
Since then, all runners have adopted the squat start, so the product of running run-up appeared in the track and field.
